The E-Jet E2 introduces a new wing, new engines and an advanced Fly-By-Wire system. Jointly these bring the fuel consumption of the E-Jet on par with the latest competition.
Complementing the lower fuel costs are reduced maintenance costs. This is an important step to keep up with competing aircraft.
Heavier engines and a larger wing increase the Maximum Take-Off Weight (MTOW) of the E190-E2. This increases underway and landing fees. If the extra range of the E2 is not needed, the higher fees can be avoided with the selection of a lower MTOW version.
